  for specifying the error handler associated with encoding to
  'output_encoding' [ticket:40]
- the Template returned by html_error_template now defaults to
  output_encoding=sys.getdefaultencoding(),
  encoding_errors='htmlentityreplace' [ticket:37]

using a more portable **exception_kwargs collection
- added "source" member to the dict propigated to Lexer/Compile exceptions
- RichTraceback can access original template source as a unicode object
using either 'source' memebr on Lexer/Compile exception, or 'source'
property on ModuleInfo, fixes #37
- unit tests for #37

  allows much simpler and hopefully bug-free tracking of 'caller',
  fixes #28

  @runtime.supports_callable exists to ensure that the "caller"
  stack is properly handled for the def.

via <%page> or default_filters (but not those within the filter)
- added buffer_filters argument, defines filters applied to the return value
of buffered/cached/filtered %defs, after all filters defined with the %def
itself have been applied.  allows the creation of default expression filters
that let the output of return-valued %defs "opt out" of that filtering
via passing special attributes or objects.
- added support for "class" structures in ast parsing (i.e. class-level
data members wont get added to the "declared" list)
